Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00012 | $0.01132 |
| Opus 5 | $0.00006 | $0.00566 |
| Sonnet 5 | $0.00002 | $0.00226 |
| Haiku 4.5 | $0.00001 | $0.00113 |
Grade A, and why
skill-health scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to skill-health — 21 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Health Dashboard
Shows a comprehensive health dashboard for all skills in the portfolio with success rate sparklines, failure pattern clustering, pending amendments, and version history.
Implementation
Run the skill health CLI in dashboard mode:
ECC_ROOT="${GEMINI_PLUGIN_ROOT:-$(node -e "var r=(()=>{var e=process.env.GEMINI_PLUGIN_ROOT;if(e&&e.trim())return e.trim();var p=require('path'),f=require('fs'),h=require('os').homedir(),d=p.join(h,'.gemini'),q=p.join('scripts','lib','utils.js');if(f.existsSync(p.join(d,q)))return d;for(var s of [['egc'],['egc@egc'],['marketplace','egc'],['everything-gemini'],['everything-gemini@everything-gemini'],['marketplace','everything-gemini']]){var l=p.join(d,'plugins',...s);if(f.existsSync(p.join(l,q)))return l}try{for(var g of ['egc','everything-gemini']){var b=p.join(d,'plugins','cache',g);for(var o of f.readdirSync(b,{withFileTypes:true})){if(!o.isDirectory())continue;for(var v of f.readdirSync(p.join(b,o.name),{withFileTypes:true})){if(!v.isDirectory())continue;var c=p.join(b,o.name,v.name);if(f.existsSync(p.join(c,q)))return c}}}}catch(x){}return d})();console.log(r)")}"
node "$ECC_ROOT/scripts/skills-health.js" --dashboard
For a specific panel only:

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skill-health is a command published in the GitHub repository Fmarzochi/EGC (51 stars, last pushed today), licensed Apache-2.0. It adds 12 tokens to every session and 1,132 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to skill-health, differing in 21 lines, and is treated as a copy.
